![]() ![]() But this final encoding is just for convenience, the underlying binary form is the actual signature that is verified. Send fan mail to authors Thanks to all authors for creating a page that has been read 116,890 times. The person may name the signature-file anything they want: the names of the file and the signature-file do not need to be similar or related. So the standard ASCII armour encoding is used to guarantee printable ASCII output. If you have not imported someones Public Key to your GPG Keyring, this procedure does not work. You are prompted to specify the type of key. ![]() ![]() Note that this is the passphrase, and not the PIN or admin PIN. Enter the GPG command: gpg -expert -edit-key 1234ABC (where 1234ABC is the key ID of your key) Enter the passphrase for the key. Here's how the GPG Suite can make encrypting email easy in Apple Mail. Insert the YubiKey into the USB port if it is not already plugged in. The message would still be readable to anyone (after base64 decoding and decompression). When you're on your Mac and you need to email sensitive information, don't let a lack of tools get in your way. If you don't do clearsign, but sign, the whole message is compressed first and then signed and the total is base64 encoded. The recipient still needs such a program to verify the signature.Īs the signature is always binary but needs to be sent in a text format sometimes, this means that the signature is encoded as base64, to ensure it's also in text format. This means that the signed message is still readable to the recipient (after the -BEGIN PGP SIGNED MESSAGE- header) which means that in a mail the recipient can still read the message without going through a PGP program. The clearsign only means that the signature is computed not over the compressed message but over the original message, if it is in text format.
